repairing, and will serve for'the temporaryrepair of leaves of springs that have been broken, and they are also capable of use for a prolonged period of time; a r

It is an object of this invention to produce a spring. leaf repairing device which will serve to hold the broken ends of the springs together and bracethe same on each side of the joint. I

A further object of this invention is to produce interlocking spring engaging plates, associated with clamps at the outer end of each plate adapted to embrace the edge of the leaf being repaired; the said clamps serving to prevent separation of the adjacent broken ends from each other.

A still furtherobjec-t of this invention is to produce a device of the character indicated which can be attached to the axle on its under side or its upper side, according to the manner mounted.

It is a further object of this invention to produce a repairing device capable of use in connection with the repair of leaves of springs where the break occurs at a point remote from the axle, and in which a part of the original securing device is employed, thus enabling the possessor of a repairing device of this character to utilize it practically regardless of the position where the fracture of the spring occurs.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which- I Figure 1 illustrates a View 1n perspective in which the spring is t cie of a fragmentof a spring, show-inga device embodying the invention applied thereto;

and

In these drawings, 10; and 11- denote the top plates, the former of which, in the-pres.- ent embodiment of the inventionyhaving a curved edge 12 forming a seat 13 in which a rib" Mon the edge o'li'the plate 11' is-seated to form an" interlocking connectionyas shown 11]. Figure '1, butotherwise, the'se p'latesare of the sameconstructiomj Each plate has aperturesflfi and 16 to. receive studs. or boltsth-at may enter apertures formed in the upper leaf 17 of the spring, which is the leaf that usually becomes impaired throughfracture. Each plate is further provided with recesses or seats 18 formed in its edges to recei ve dowels 19 that are carried by the clamp members 20 and 21, the. said clamp members being arranged in pairs and connected by a bolt 22. whereby they may be drawn together into engagement with the edges of the leaf of the spring being repaired.

Each clamp member has a channel 23 forming a seat for the edge of the leaf of the spring, and when the clamps are in place, they cannot be displaced vertically on account of the fact that the flange 24 formed when the channel is produced, fits under the leaf of the spring, and the frictional engage ment of these clamps prevents the lea-i sections from parting. The plates 10 and 11 are furtherheld in place by a clip which comprises a base plate 25 and the vertical U-shaped elements 26' of conventional construction. v

When the device is to beemployed in connection with springs that are suspended under the axle of an automobile or vehicle, the inventor prefers to employ filling blocks 27 r and 28 between the elements 26 and joint between the plates, in orderthat there will be an increased bearing surface to be-engaged by the under side of the axle, the advantage. of which will, it is thought, be apparent.

A device made in accordance withthis in vention, while primarily employed as a repairing device, is also of pronounced utility as a relnforcing device for a spring, serving lir ing its flexibility. It also acts as a shock absorber, preventing excessive rebounding of the spring when the spring is subjected to unusual action. l/Vhen the springs on each side of the automobile are supplied with the device embodying the invention, they will prevent rocking of the automobile and the automobile will ride more smoothly and will run in a more direct line, without requiring action of the steering mechanism.

It will be seen from an inspection of the drawing and from the foregoing description that a repairing device embodying this invention can be expeditiously applied to springs, and that they, of course, may be made of different sizes or dimensions to be employed in connection with light or heavy springs, the principle being the same regardless of the dimensions.

I claim:

1. In a spring repairing device, plates having interlocking engagement at their inner edges, clamping elements connected to the edges of the plates near their outer ends, means for drawing the clamping members into engagement with the edges of a spring,

and means for holding the plates in assembled relation to a spring.

2. In a spring repairing device, plates having interlocking engagement with each other, the said plates having recesses in their edges near their outer ends, clamps fitted against the edges of the plates, means extending through the clamps and seated in the recesses for holding the clamps in operative relation to the plates, means for drawing the clamps against the edge of a spring, and means for holding the plates in assembled relation to the spring.

3. In a spring repairing device, plates having interlocking engagement with each other, the said plates having recesses in their edges near their outer ends, clamps fitted against the edges of the plates, means extending through the clamps and seated in the recesses for holding the clamps in operative relation to the plates, means for drawing the clamps against the edge of a spring, means for holding the plates in assembled relation to the spring, and filling blocks on the upper surface of plates.
